Discharging And Recovery
DISCHARGING AND RECOVERY
NOTE: Use of a refrigerant center is recommended to carry out recovery, evacuation and charging of the refrigerant system. If a refrigerant center is not
available, refrigerant system recovery, evacuation and charging may be accomplished using a separate recovery station, vacuum pump, charging meter
and manifold gauge set.
NOTE: Leaks in refrigerant system equipment, hoses or gauges can cause a leak in vacuum that may be misinterpreted as a problem with the vehicle
refrigerant system. It is necessary to leak-test all refrigerant system equipment, hoses and gauges on a weekly basis to verify that no leaks are present.
1. Prior to recovery, you must verify the purity of the refrigerant. See See: Testing and Inspection/Component Tests and General
Diagnostics/Refrigerant Identification Testing.
2. Connect an R-134a refrigerant center to the low- and high-pressure gauge port valves following the operating instructions provided by the
equipment manufacturer.
3. Recover the refrigerant from the system following the operating instructions provided by the equipment manufacturer.
4. Once the refrigerant has been recovered, switch the power supply OFF.
5. Allow the system to set for approximately 2 minutes and observe the system vacuum reading. If the vacuum is not lost, disconnect the recovery
equipment.
6. If the system does lose vacuum, repeat Steps 3 through 5 until the vacuum level remains stable for 2 minutes.
7. Carry out the required repairs.
